![]() AUTO is the preferred option as hibernate will chose the best strategy for us without any parameters is same as without having it. Other values are IDENTITY, SEQUENCE and TABLE, which are actually dependent on the database that you use. You can also specify a strategy on how the values will be generated like AUTO is the default if you don’t give a strategy. You can use it along with and make your primary key automatically generated rather than setting each time. ![]() Therefore you don’t have to set it manually. One of the applications of this difference between entity names and table names is the use of them within HQL(Hibernate Query () over the id field tell hibernate to make this field as the primary key of the you use then hibernate will automatically generate values for that using an internal sequence. is different from (name=”XYZ”) in that changes only table name and entity name still remains the default, which is class name. With and in the absence of an annotation to change the table name, the entity name will be used to create table instead of class annotation ( /) tell hibernate to create table with name XYZ instead of class name. By default, hibernate generate the table name same as classname with only an annotation. This will change the identity name to XYZ. We have to use annotations corresponding to its attributes/values to get the same result. The hibernate specific Entity annotation has been deprecated in hibernate 4. Here we will discuss most commonly used basic annotations in hibernate - and annotation () over the class tell hibernate to treat this class as our entity class that needs to be saved.
